What is the volume of a right circular cylinder with a diameter of 46.25 cm and a height of 18.5 cm?

alexdok [17]

Radius = <span> <span> <span> 23.125 </span> </span> </span> cm
Cylinder Volume = <span>π <span>• r² • height
</span></span>
Cylinder Volume = 3.14 * 23.125^2 * 18.5

Cylinder Volume = <span> <span> <span> 31,064.53515625 </span> </span> </span>

Cylinder Volume = <span> <span> <span> 31,064.54 cubic centimeters

Answer:

$y=e^{-3t}(A\: cos\: t+B\:sin\:t)$

Step-by-step explanation:

<u>Given Second-Order Homogenous Differential Equation</u>

$y''+6y'+10y=0$

<u>Use Auxiliary Equation</u>

<u /> $m^2+6m+10=0\\\\(m+3)^2+1=0\\\\(m+3)^2=-1\\\\m+3=\pm i\\\\m=-3\pm i$

<u>General Solution</u>

<u /> $y=e^{pt}(A\: cos\: qt+B\:sin\:qt)\\\\y=e^{-3t}(A\: cos\: t+B\:sin\:t)$

Note that the DE has two distinct complex solutions $p\pm qi$ where $A$ and $B$ are arbitrary constants.

Use the explicit formula an = a1 + (n – 1) • d to find the 250th term of the sequence below. 57, 66, 75, 84, 93, ...

strojnjashka [21]

The general term of an arithmetic sequence is,

$a_{n} =a_{1} +(n-1)d$

Where , $a_{n}$ = nth term.

$a_{1}$ = First term

and d = common difference.

The given sequence is: 57, 66, 75, 84, 93, ...

Here $a_{1}$ = 57,

d = 66 - 57 = 9

We need to find the 250th term. So, n = 250.

Next step is to plug in these values in the above formula. Therefore,

$a_{250} =57 +(250-1)*9$

= 57 + 249 * 9

= 57 + 2241

= 2298

Therefore, 250th of this sequence is 2298

Hope this helps you!
